After having a Belkin audio receiver (F8z492cw) whose audio quality was unsatisfactory, I passed this Philips model. The audio is much better here because this receiver integrates an AAC codec for iOS devices and APTX codec for other devices equipped. Suddenly, the Bluetooth on your device sending digital data that is decoded by the device and allows for optimal sound quality (this is still bluetooth). Another advantage is the possibility Multi-peer lets you juggle your various devices without musical break. A purchase recommended.
